Explanation

Since fluorine is more electronegative, its oxidation state is -1.

The molecule OF2 has zero overall charge:

O + 2F = 0

x + 2(-1) = 0

x - 2 = 0

x = +2

Explanation

 A calorie is a unit of energy, specifically used to measure heat energy.

1 calorie is the amount of heat required to raise the temperature of 1 gram of water by 1°C.

In dietary terms, we use kilocalories (kcal) — where 1 kcal = 1000 calories — but it still measures energy, not diet or food itself

Explanation

According to Coulomb's Law, the force between two charges is inversely proportional to the square of the distance between them.

If the distance is halved, the force becomes four times stronger.

Explanation

Explanation

Femto (f) is a prefix in the metric system that represents 10⁻¹⁵ (one quadrillionth).

It is commonly used in physics and chemistry, such as femtoseconds (fs) = 10⁻¹⁵ seconds.
